The door 3 may be provided with any suitable handle land is carried by-a rectangular frame or mounting 5 which carries on the inner side thereof, groovedrollers 6 disposed at the several corners, and

which engage tracks 7 spaced outwardly from and carried by the side of the refrigerator car 1.

The door 3 may be provided with suitable locking means, and in this instance, rack bars 8 and 9 aresli'dable in the door and may be actuated by apinion 10 which 192 seria no. 1119 5 53 sockets 12 andl3'iesp'ectiv'ely, in the'top and bottonrsides-oi the openingQQ.

when the door-3 is closed the links are disposed in extended position, but when the door 3 is withdrawn from the opening 2,

the links are disposed-in the position indi cated in Fig. 6, thus permitting the doorto 'be drawn straight out fromthe opening 2.
